Thursday (last night) I did intervals, then more on the elliptical, for about 3 miles in 45 minutes. I was not as energized, but not too awfully draggy. I felt pretty tired by the time I finished, though, and definitely felt weary later as I climbed the stairs to my apartment.
This morning, my calves actually feel tired. I am debating seeing what kind of distance I can get tonight; I'll be away over the weekend, possibly without much exercise, so more exercise now might be good, but I don't know if I should push it. On the other hand, I am curious about how much I can accomplish.
It's nice to know I'm capable of more than I thought I was, at least! I wonder if I can build up a bit? Either faster, or more time? Recommendations for which might be best to try first?
